Title: Optical switch
Inventor: SUZUKI KENJI
IPC: G02B6/12
Filed: 2003-04-09
Abstract: <P>PROBLEM TO BE SOLVED: To provide an arm heating Mach Zehnder interferometer optical waveguide switch that is reduced in dependence of a switch extinction ratio onto the polarization state of input light.  <P>SOLUTION: An optical waveguide 9 is composed of a core 2a and clad 2b, which are formed of polymer, respectively. The increase of compressive stress in a direction X parallel in a Si substrate surface 1, which is caused by the difference of thermal expansion between the Si substrate 1 and optical waveguide 9 when heating the optical waveguide, is concentrated on an area 10a of the bottom of a groove structure 4 by arranging the groove structure 4 at both sides of the optical waveguide 9. Consequently, the stress is opened up to the side of the groove structure 4 and upward of a heating electrode 3 on an upper area 10b of the groove, thereby reducing the change of the stress applied on the optical waveguide 9.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
